DUST-GUARD FOR JOURNAL-BOXES.

SPECIFICATION forming part of Letters Patent No. 742,750, dated October 27, 1903. Application filed January 10, 1903. Serial No. 138 ,540. (No model.)

T at whom it may concern: in thevertical limit of the box. This affords Be it known that 1, JOHN W. STEPHENSON, ample room between the ring and the carof Toledo,in the county of Lucas and State of wheel to enable the ring to be set in place Ohio, have invented a new and useful Dustand removed. The providing of room for Guard for J ournal-Boxes, of which the folthis purpose is an important feature of my lowing is a full, clear, and exact description, invention and distinguishes it from all prior reference being had to the accompanying devices known to me, in which the complicadrawings, forming part of this specification, tion of the parts and'the narrowness of the in whichspace afforded for access to the ring rendered 1 to Figure 1 shows in vertical'longitudinal secthem very objectionable. The ring 5 is held tion an axle-box having a dust-guard conin place by a cover-ring 8, which preferably structed in accordance with my invention. also fits within the recess 6, and the ring Sis Fig. 2 is a vertical section on the line II II of retained by means of locks9, which are piv- Fig. 1.

The springs serve notonly to hold the locks but none of them, so far as I know, have given against the retaining-ring 8,but also to hold the entire satisfaction. Most of them have been cover-plate 7 to its seat on the box.

The skilled mechanic will be able to modify the parts of the device in many ways without departure from my invention as defined in the following claims.

I claim- 1. In combination with a journal-box, a cover-plate, a dust-ring extending within the vertical limit of the box, and means on the box for holding the dust-ring in place; substantially as described.

2. In combination with a journal-box, a cover-plate, a dust-ring extending within the vertical limit of the box and set in a seat accessible from the back of the box, and a lock attached to the rear end of the box and adapted to hold the dust-ring in place and movable to free the dust-ring; substantially as described.

-3. In combination with a journal-box, a cover-plate, a stationary dust-ring fitted in a recess in the cover-plate accessible from the back of the box and extending within the limit of the box; substantially as described.

4. In combination with a journal-box, a cover-plate, a dust-ring extending within the vertical limit of the box cessible from the back of the box, and a lock and set in a seat ac- 6. In combination with a journal-box, a

- cover-plate, a dust-ring adapted to fit around the axle, a lock pivoted to the box and adapted to hold the dust-ring in place, a bolt on which the lock is pivoted, and a spring on the bolt; substantially at described.

7. In combination with a journal-box, a cover-plate, a dust-ring adapted to fit around the axle, alock attached tothe box and adapted to hold the dust-ring in place, and a spring which holds the lock, said lock having a projection adapting it to hear at the ends on the dust-ring and against a fixed bearing; substantially as described.

In testimony whereof I have hereunto set my hand.
